Presidents’ Day is a holiday for Grub Street, but, thankfully, there’s enough in this week’s magazine to read till we return tomorrow. Daniel Boulud, whom Adam Platt respects as the Last Great French Chef, falls down in his new restaurant and gets only one star. In this week’s “Openings,” Rob and Robin introduce us to Olana (American with Italian influences) and marvel at Akhtar Nawab and Noel Cruz for putting a restaurant where Jimi Hendrix used to (reportedly) play. At Momofuku Ssäm Bar, Rob and Robin find the mind-bending “Frankensteak”: hanger steak that is literally glued to world-class rib-eye deckle. The Insatiable Critic falls for Fiore, a funky, rustic Italian place in Williamsburg; for those at risk of scurvy, pickled lemon is in “In Season” this week. But if you want a drink, you’ll find a guide to the city’s top boutique wineshops by the Gastropoda herself, Regina Schrambling.
